SECTIONAL BOOKCASE.

SPECIFICATION forming part of Letters Patent No. 715,243, dated December9, 1902.

Application filed January 30, 1901. Serial No. 45,290. (No model.)

To ailwwm z may concern,.-

e it known that I, PHILO WILLIAM CAS- LER, a citizen of the UnitedStates, and a resident of Littlefalls, in the county of Herkimer andState of New York, have invented certain new and useful Improvements inSectional Bookcases, -oi which the following is a specification.

The present invention relates to an irnprovement in sectional bookcases,and has special reference to a novel and useful equalizing device forpreventing the sliding door from binding, as hereinafter fully setforth.

Referring to the accompanying drawings, in which similar letters referto similar parts throughout both views, Figure l is a sectional view oftwo interlocking crates or cases provided with my improvements. Fig. 2is a plan or top view of the upper case with the door pulled out, thedotted lines in this view showing the position of the equalizer when thedoor is slid into the case.

A represents the bottom, B the back, and C the sides or ends, of thecases. For the purpose of having the cases interlock with one anotherthe lower portions of each back is provided with a recess B', adapted toreceive the upper projecting portion B2 of the adjoining section.

D represents the door, which is pivotally mounted in the front portionof the case by means of hooks D', engaging stops E, located on the innersides ofY the ends C. When brought to a horizontal position, this doorslides into the case and is supported by horizontal rods E2.

Mounted in the upper portion of the case is an equalizer for the door,comprising two arms F, which cross each other and are pivotallyconnected at their central portions. The forward ends of these arms havereduced inwardly-curved portions F', which are slidably mounted ineyelets G, secured on the door. The inner ends of the arms F arepivotally connectedwith the back of the case by means of brackets H andintermediate links The curved front ends 5o Connecting the centralportions of the arms 6o F is a spiral spring F2, whereby the door isdrawn rearwardly when raised to a horizontal position.

In order to provide a dust-proof joint between the door and the case,the door is provided along,` its edges with a strip of felt I, thecentral portion of which is forced into grooves on said edges, the edgesof the felt projecting at right angles to the edges of the door.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A section of a bookcase comprising the sides, the bottom and back, apair of guide or supporting rods connected to the sides near the upperedge thereof, a door connected to said rods and adapted to be supportedthereby,l eyelets secured to the rear end of the door, a pair of armspivotally joined together provided with reduced curved ends which iit insaid eyelets, a pair of brackets secured to the back of the case, a pairof links pivoted to said brackets and the inner ends of the arms, and aspring connected to the back of the case and to the arms at theirpivoted joint to hold the arms in a compressed position.
